Attempts were made to compare the adsorption efficiency of coconut shell-based granular activated carbon with the adsorption efficiency of commercial carbon, Calgon carbon F-300, with respect to adsorption of organic matter from a beverage industrial wastewater. Freundlich adsorption isotherm was used to analyze the adsorption efficiencies of the two activated carbons. These studies indicate that acid-activated coconut shell carbon had higher adsorption for organic matter expressed as chemical oxygen demand, (COD), than barium chloride-activated coconut shell carbon and Calgon carbon (F-300) at all carbon dosages used. Thus, the potential for using agricultural waste (coconut shell) that litter our environment may be valuable resources for removal of organic matter from industrial wastewater.
Key words: Coconut shell, activated carbon, COD, beverage industrial wastewater.
